Adapter Good for Older Vehicles
This car adapter works well in older vehicles that do not connectors for cellphones. Cable is provided to plug into the AUX for the car radio and a Type C connector for cellphone. The sound is very good and can use as hand-free device for phone calls. No ambient noise on calls and clear sound for listening to music, podcasts, audio books, etc. Good product.

Works well, good range.
Easy to use. No protruding buttons (to mess with your music while the receiver is in your pocket). Pairs easily. Good sound quality.

Great! Except Calls
Have never had a problem with trying to get it to connect. Still works when charging, and is always in my car. Sound quality and noise levels are great. I don't normally call when in the car, bit I've noticed that my phone will default to the UGREEN microphone, which is annoying. Not great for calls, but it's great for normal music functions.

It Works! And Sounds Fine
I finally have Bluetooth in my 2014 Mazda CX-5! I just wanted to be able to play audiobooks and music from my phone without having to connect a thousand cables first, and for that this thing is spot on. Pairing this adapter with my Moto Stylus 5G (with Android 12) was easy, and now it automatically connects every time I get in my car. I also had no trouble connecting the adapter to the car itself; the center console storage ... box?... thingy?... has the aux port - a standard headphone jack - and a usb port, so I just leave the thing plugged in in my center console all the time. I have not tried making a call with it nor have I done anything else with the microphone so I can't rate those features yet. However, for being able to play audiobooks and music from my phone via Bluetooth, this does exactly what I wanted. And, fwiw, I have not noticed any sound distortion with spoken word or music (although the stock radio in the Mazda isn't great to begin with, so who knows). My only beef with this adapter is that you can't turn it off. This is annoying and potentially problematic. For one, the range is really high and I keep finding that it remains connected to my phone even once I'm inside and upstairs, with my audiobook or podcast playing without me realizing it. Sure I could unplug the USB cable, but the battery holds a charge for a few hours so that doesn't solve the problem. Plus, I don't want to have to fiddle with cables the next time I get into my car. My biggest concern, however, is that if it's always on, then it's always pulling a little bit from the car battery even when the car is turned off. I doubt that the draw is enough to significantly impact the battery in the short term, but what if I go out of town for a few weeks and forget to unplug the adapter from the car before I go? That said, I'm still happy with this little adapter. It does exactly what I wanted it to do, it was very easy to set up, and it doesn't negatively impact audio quality, at least for me. I just wish I could turn it off.

Good Price, Easy Hack
I purchased this to replace an FM Bluetooth transmitter in my car (for privacy reasons). Others I searched for didn't have a microphone, making hands free driving while talking an issue, but this does. It worked great, is small, and has not had any issues with connecting/disconnecting. Except one small issue, possibly unique to me. It doesn't power off when it loses power. What that means is after I turn off my car and walkway the connection remains. My music or podcast still playing, and the connection is quite strong. This draining my phone battery faster. To correct this, I opened the case (prying between the sides and the back of the unit). Then removed the battery by disconnecting the small metal leads to, what I assume is, a small power controller. Leaving the controller on the wires to the main board I closed it up. Now the unit only powers on when given power the the USB-C port and turns off when the car turns off. Perfect for what I need at $10 and under 10 minutes of work.

It’s good.
It’s scared me a few times. But it works good. You can not use it for the phone even tho it has a mic , it’s not very good. Other than that I have only had one problem where it didn’t work for a while , but it came back

Perfect for hooking up music to an amplifier for parties!
Works great, easy to pair, has great range, and sounds great! Stays charged for a VERY long time (many hours). I don't know just how many, because I haven't run it completely out yet. I use it for parties where we need music running, so I've run it for 4-5 hours straight with no problems. Hooked up to an amplifier, and there wasn't any connection noise, etc. — just great sounding music!

It worth the price
Really good product. the audio quality is great! also you have the option to use it connected to the power supply or simply use it wireless, it worth the price for sure, and is not hard to configurate, just as a regular BT device. Also it comes with Mic so you can use it for making calls.

It works as specified. Connection and pairing bluetooth between my iPhone and an old Panasonic mini-Hifi set went without any glitches (so far). I find the sound quality quite good as compared to a wired connection from my phone to the hifi audio port. The song continued to play when I bring the phone 3 - 4 metres away and behind a wall. The item was made in China. I do not know how long it will last, but so far so good. Item was delivered the next day after ordering and payment.

2014 Model Polo aracımda kullanıyorum. Gayet hızlı bağlanıyor. Bağlantıda kesilme, kopma vs yok. Aux çıkışlı güzel bir bluetooth bağlantı cihazı almak isteyenler için tavsiye edilir.
